increased from 40 to 45 litre and -the presaure of
the upper seal on the mixture is 4.3 kwom (Fig. 9).
Good results were obtained when natural rubber was
plasticised in the mixer; the temperature of the
rubber was increased from 140 15QOO after process-
Ing for 3 minutesp and to 155 18000 when the time
of, the experiment was Increased from 5 to 7 minutes.
6.4 minutes processing was required to achieve a
p-asticity.of 0#37 -76,40 (Fig.11). When natural
rubber was plasticised-in the presence of accelerators
a 0.45 plasticity (according to Karrer)owas obtained
after 3 minutes at a temperature of 145 0. Experi-

Title Apparatus for determining the moisture content of wood
d"i6al Sbor. mat. o nov. tekh. v strol. 3, 20-21, 1954

Abstract This apparatus is built on the principle of measuring the
electrical.resistance of wood by passing through It an
electric current depending upon the content of moisture.
The electrical resistance will decrease with the increase
of moisture, This apparatus is used to check members of
wooden structures where the moisture content usually is
in the limits of 10 30%.

"Short-wave Techniques." The following topics are covered:
propagation of short waves, electron tubes, short-wave
receivers and transmitters, radio-telephone, antennas,
measuring equipment,:ete. In additiOn, contains theoretical
aspects, plu8,radio amateur jargon, Morse code and long-
distance communication procedure.
Author of book, '.'Radio Amateur Handbook," The book contains
following topics:- Ohm's law, resistance, galvanized
elements and storage-batteries, electromagnetic Induction$'
alternating ctu-rent, self-induction and capacitance,
oscillations, antennas and ground, etc. This book is
a very useful aid for radio amateurs on all levels.

ABSTRACTs f amplifying electronic tube# is-
One of, the main parameters o
the transconductance which characterizes the controlling ac-,
tion of the grid, i.e. its influence on the electron flux.,
As a result,of.:Iengthy research It-has proved possible.to.
manufa,cture,receiving tubes Including low-power amplifiero
with an increased-transconductance. The development of the
tubes was.conducted in 3 directions. The first direction
included Vdacrease in the distance between the controlling
grid-and the cathodq to several tens of microns. The second.
direction was using a tube with'the so-called cathodic 'grid
located between the controlling grid and the cathode, with
a cer
tain::positive potential (Fig. 1). In the third direc-
,
tion a., high trans-conductance was obtained by means of a.
second electronic emission. Only recently were materials,
found which-produce a heavy and steady siecond emissiono-Good.
results were also obtained in respect to increasing the se.r-
Card 1/2- vice life, the mechanical durability and reliability of the

ectronic Receiving Tubes including Low-Power Amplifiers
tubes. The so-called,Bar-type tubes (st,erzhnevaya lampa)
developed in the USSR under the aupervision of V N.~Avdey-
ev are of.speciall interest. Each grid in them ~as an,..un-
Usual design inthe form of 2 bare between which theelec-
tronie flux passes to the anode (Fig. 3). In the bar-type
tubes, the control of.the electronic flux is 'based on the
principles of electronic optics. The manufacture of bar-
type lamps is muchnimpler.than those with spiral grids.
While,working:on the improvement of bar-type tubes, V.N.
Avdeyev succeded in-making another kind of new tube.with,
so-called pressed grids having the form of frames.pressed
from sheet metal.. The principle of their construction is
shown-jn fig. 4- 'The difficulty in obtaining a high trans-
conductance is a deficiency of the bar-typo and pressed tubes.
It.does not.exceid at present several units of milliampere
to the volt. There are 5 diagrams.
